Twixtor Vs Optical Flow FCPX

In my opinion if your footage isn't going to work with optical flow, twixtor will only make it marginally better. For what it's worth I would save my money or spend it on other plug-ins. Motion estimation software can have some amazing results, it just doesn't work well with a lot of the content I deal with.

On the plus side, it renders a hell of a lot faster in X then it does in 7.
